Systems that are certified for cyst reduction may be used on disinfected water that may contain filterable cysts.

I’m always a little afraid to order substitute brands, but theprice and the picture of thePurFilterproduct gave me a little more confidence to give it a try. But once here it fit my Kitchenaid Side-By-SideRefrigerator perfectly and was easy to install. Would recommend this replacementproduct to others. PUR QTSS Whirlpool Quarter Turn RefrigeratorIce and WaterFilterCartridge
It has a removable catridge that is replaced every 6 months, no screwing, it just slides and snaps inon its own. This new catridge has been infor about a month or two and suddenly last night thewater tasted like nasty chlorinated faucetwater. I had more waterthe next morning and it still tasted awful. So I took the catridge out and put it back in, ran water through then tried another glass and it tasted beautiful. What happened and why? Will it do this again? Please help!
